Chemical reference standards are particularly important for analytical chemistry since most analytical instrumentation is comparative; it requires a sample of known composition (reference standard) for accurate calibration. Whether a single or a multi-component mixture, these chemical reference standards are produced under stringent manufacturing procedures and differ from laboratory reagents in their certification and the traceability of the data provided.
